Responses of Trophic Structure Variation in Fish Assemblage to Hydrologic Regulation in a Tributary of the Three Gorges Reservoir, China

Abstract: Responses of trophic structure to reservoir regulation are important to manage and conserve the river ecosystem influenced by dams. We used stable isotope-derived community-wide metrics to describe spatiotemporal variation in trophic niches and trophic structures of fish assemblages in a tributary of the Three Gorges Reservoir (TGR) in China where water level regulation is put into operation annually. A longitudinally increasing trophic space was discovered in this tributary especially when the water level was… Show more
